In early summer, night falls at its latest hour—around 9:30 to 10 PM. Not a single bright planet is around.

On Sunday night, May 15, a gorgeous total eclipse of the Moon will sweep across the continent. It’s especially welcome since it’s been years since we’ve had a true total lunar eclipse. Get the “real” start time and more viewing tips.
For the last couple of years, every lunar eclipse has been of the penumbral type, meaning the Moon failed to even momentarily touch the edge of…

This weekend marks the new Moon stage of the lunar cycle, which means we will be viewing crescents until then. Seen in twilight rather than full darkness, and always low in the sky, the crescent may be the Moon’s most surreal phase. Learn more.

Until then, we enjoy a waning crescent all…
